Bravo Cardinal Burke and Cardinal Caffarra. I am sure that these brave cardinals will find much support from others. Cardinal Casper's proposal is destined to wither and crumble. I would be shocked if it gains traction.
There already exists a process to reconcile those in unrecognized relationships. Catholics in such situations (unrecognized relationships) should familiarize themselves with it. Those that TRULY desire recognition will be open to an honest resolution and will seek discernment and come to know and embrace the outcome; those that don't will continue with whatever they have made.
Cardinal Walter Brandmuller-" Neither human nature nor the Commandments nor the Gospel have an expiry date" Courage is needed to enunciate the truth even against current customs. Whoever speaks on behalf of the Church must possess courage if he does not want his vocation to be a failure. The desire to obtain approval and applause is a temptation which is always present in the transmission of religious teaching."
Cardinal Ruini- "It would be a fatal mistake to follow the pastoral approach without referring to doctrine."
So much to say on this. Nothing I have written is "my opinion." What is written here are teachings of the Church that are scriptural. All we can do is pray for the discernment, strength, & trust in Him that we can follow His teaching to get the prize that we are to keep our eyes on--that is the Kingdom of Heaven for us all.
If God were our one and only desire we would not be so easily upset when our opinions do not find outside acceptance.
